The Halemba coal mine is a large mine in Ruda Śląska, Silesia, in southern Poland. Its name sadly made the headlines in November 2006, when an explosion resulted in 23 fatalities.
The photo above shows the office building in 2004, with a large green logo in New Zelek on its facade. By June 2012 (see Google Maps), this logo has been replaced with a more generic sign by Kompania Węglowa S.A., Europe’s largest coal mining company founded in 2003. However, there are still a few other vestiges in Bronisław Zelek’s idiosyncratic 1970s typeface, see below.
